1o all whom t 'may con/cern:

Be it known that l, FRANK PELrKAN,-a citizen ot theUnited States,-residing the city and county of San Francisco and State 6 of California,have invented a new and useful Improvement in a Tellers Gage, ot whichthe' 'tollloWin-g is a', specification.

`My invention rotates: to improvementsin te-llers cages for banks andthelike wherein ru movable shutter for al customers vvindonr isoperatcdin con-junction with a boothand door arranged outside oit safidWindow to perniitv access to the Window to only one per'w son at a timeand to prevent the* escape of a person from' `the lWindow yin event or"attempted robbery. V

The primary object of my invention is to provide an improved telierscage for banks and the like which Will ir'l'liordprotection againstrobbery and prevent the escape of persons attempting to Yroh or `defraudthe ban-k. y

Another object is tofprovifde' an impro-ved rafge Which/Will alford'privacy to customers -ifnl transacting business ivith'the bank. y

A further object is kto`r provide animproved tellers cage ot thecharacter described wherein a shutter normally closing acustomers'window of said-cage`can he opened only when th'e'do'or to abooth arranged outside of *saidl Window is locked whereby thev teller isprotected `from attack by persons other than a single individual withinthe' booth.

Referring. to the drawings the numeral l is usedI to designate invgeneral the counter ot' a tellers cage having partitions' 9. sepa?rating' said cagev Vfrom adjacent cages and having. oneo'r moreciis'torfers Windows 3. through which business is transacted Ibetweenthe .teller and customers" of thefban'k. A booth i isprovided outside ofeach Window 3. Doors 6 are mounted in connection With thefbooth to openand close entrances 7 provided therein. Eachcage is pre1 erably providedWitht'ivo Windows 3 positioned adja cent the cento ofthecage andthe hool's'arranged outside Lof said' vvii'idoivs e' sepa'- 'rafed' byapar-ation s' arranged between-trie 110 Windows, but this particulararrangement may of course be modified in various ways to meet therequirements of any particular installation.

A shutter 9 is mounted in connection with each window 3 for opening andclosing the same, said shutters being'k provided with mounting elements11 threaded onto threaded shafts 12 mounted within the upper portion ofpartitions 13 across the front of the cage. Y Suitable electric motors14 are mounted. adjacent the ends of the shafts 12 and connectedto saidshafts for imparting rotation thereto whereby the elements 11 may bemoved longitudinally along the shafts to move the shutters to open orclosing yrelation to the windows 3.

Each motor '14 is connected to a suitable vsource of power 15 through a*reversing control switch16 mounted in any suitable llocationconveniently accessible to a teller within the cage but kinaccessible toa person in a booth 4. Current is directed by the reversingswitch16`through independent opening and closing circuits as showny in Fig. 5of the drawings whereby the current from the source of power is directedin opposite directions through the motor to cause a rotation of saidmotor in a direction adapted to obtain the desired movement of theshutter 9 associated therewith. y

The opening circuit consists of a connection 17 extending fromoneterminal 18 "of theswitch 16 through a pair of contacts 19 arranged'tobe bridged by a contact plate 21,

' to complete a 'circuittherebetween. yFrom the contacts., 19 thecurrent is conducted |througha connection'22, switch 23, andconnection`24` to aconnection 26 connectedV to the motor 14 and thence'through'a connection 27 toa return contact l28 of the switch 16. i

'Ihe closing circuit consists of aY connection 29k extending fromterminal 34 of the yswitch 16 to the connection 27 whereby currentisdirected in opposite direction to and through the motor 14. From themotor the current is Vconducted through the connection 26 and a switch32 and connection v33 to a return contact 31 of the switch. y

The switches 23 and 32,V which may be of any suitable constructionadapted to norvmally close 'the circuit therethrough, are

mountedv in positions adjacent the extreme positions of opposite edgesofthe shutter9 and are arranged to be actuated by the movement of theshutter into' engagement therewith to break the circuit` by virtue ofwhich the shutter isat thevmoment being actuated.

The contacts 19 are resiliently mounted within a partitionof theboothadjacent the free-edge of the adjacent door 6, preferably at widelyspaced points, said'contacts preferably being in the form 'of buttonsextending outwardly slightly through the facing of the partition inposition to be engaged by the contact strip 21 which is set into theedge of the door in such manner as to engage both contacts and completea circuit therebetween only when the door is in fully closed position,the purpose of this'arrangement being hereinafter more fully explained.vt

The doors 6 may be made either' of the swinging type as shown in Fig. 1of the drawings or of the revolving typeas shown in Fig. 2. In eithercase the doors are arranged to be moved by gravit-y to a normally fullyclosed position. This is accomplished in the case of a swinging door bymounting the door upony the well known self-closing hinges 35 wherebythe weight of the door acting upon inclined edges ofthe hinge buttsoperates to swing the door closed when said door is swung outwardly fromthe closed position. In the case of a revolving door I provide a floorplate 36 hav'- ing a central recess 37 `forming a mounting for the lowerend of an axis about which the door is revolved. The plate 36 isprovided with a fianged edge 38 adapted to form a track for rollers 39mounted upon the bottom ofthe door, said flange having an undulatingupper surface forming low points 41 defining closed positions for thedoors. The vflange is provided with convex arcuate track portions 42between the low points whereby the weight of the door supported upon theconvex surface by the rollers will cause the door to move to the nearestclosed Vposition as defined by low points in the flange, the rollersresting in said low points until the door is partiallyk revolved toadmit a person to the booth. In this form of door,

Vfour door portions are preferably arranged about a. commonfaxis, saiddoor portions being arranged at right angles to each other and the axisso positioned that two of the door portions will act as partitions forthe booth at all times' as shown in Fig. 2 of the drawings. A contactstrip 2l is mounted within the outer edge of each door portion so thataconnection will be made between' the contacts 19 when any door portionis vmoved adjacent thereto.

Bars 43 are pivotally mounted within suitable bearings 44 positionedwithin the upper portion of the partition 8. Each bar 43 is providedwith an extension 46 at one end adapted to be moved into engagement witha notch 47 formed in the upper edge of theadjiacent door whereby saiddoor may be locked in closed position. An extension A48 is formed uponthe opposite end of the. bar and `is arranged to be engaged by theadjacent shutter mounting element 11, or other suitable element movingwith the shutter when said element is moved to the closed position, formoving the bar pivotally within the bearings 44 and thereby causing theextension 46-to be moved out of engagement with the notch `47 to releasethedoo-r. The bar and extension are so mounted that the weight of theextensions will normally cause the extension 46 to be moved downwardlyby Vgravity into engagement with the door andtomaintain lockingengagement therewitlr until;- released by movement of the shutteragainst the extension 48 when the shutter is closed.

In operation my invention is as follows: The shutter 9 of any particularwindow is normally kept closed to protect the teller fron-1- observationand possible attack by robbers. `While in. the closed position theshutter holids the bar 43 in door releasing position so that the door 6of the booth 4 adjacent such window may be opened to admit a customerinto the booth. When a customer enters the booth to transact businesswith the teller, the teller moves theI switch 16 to engage the contacts18 and 28', thereby directing current through the shutter openingcircuit as indicated by the arrows in Fig. 5 of the drawings to operatethe motor 14 in a' direction adapted to move the shutter along therotating shaft 12 to an openposition as indicated in dotted lines insaid Fig. 5; Before it is possible Afor the circuitto be completed tothemotor 14 it is necessarythat the door 6l of the booth be in fullyclosed' position whereby the contact strip 21`will be caused to bridgethe contacts 19.

Aisth'e shutter 9` is moved the extension 4S of the bar 43 Awill beYreleased an'd the weight of said extension and the extension 46 willcause the extension 46 to drop into the' notch 47 ofthe door therebylocking said dcorin closed position solong as'the shutter remains open.The customer is nowV locked within the booth' and may transact hisbusiness' ingprivate with the teller through `the opened window 3of thecage. When the business has'been completed the teller moves the controlLswitch 16 to` engage the contacts 31 and 34 thereby closing the circuitto the motor14 and directing current through said motor in a directionopposite to that resulting in the opening of the shutter. The motorisnow rotatedE and the shutter 9 moved along the shaft 12' to closedposition. As the shutter approaches the'` closed position, the"extension 48 of'the bar 43 engagedvand the bar moved to causetheiextension- 46 torelease the doo'rand th-erehy permit the customer toleave the booth.

The switches 23 and V32 placed in the opening andE closing circuitsrespectively are operated'as above explained bythe movementof the'shutter to either eXtreme position to break thev then actuating circuit.Thuswheir the window is being opened the 4actuatingcircuit will beclosed until the instant' the shutter reaches the extreme positienauchoperatesithe swift-oh 2`3f'to break the circuit and prevent furthernrovement of the i slirutter. rlzhe opening circuit is now broken at theswitch 23' and the Closing circuit brolien at the switchlk so that bothcircuits remain inactive so long as the shutter remains in ope-nposition'. When now the switchl isv o}f erated to close the shutterclosing circuit, the movement 0f the shutter away fro-1n the switch23will` release said switch to circuit closing position. The currentthrough the circuit containing the switch 23 will however be mow broken'the switch 16 sol that no current will be directed through the openingcircuit connections. The switch 32 operates 'in identical manner tobreal the aoy tuatingl circuit when the shutter reaches the extremeposition and to restore a closed connection through .said switch as soonas the circuit therethrough is broken at the switch 16. In this mannerthe lswitches 23 and 32 Vare made to operate in conjunction with thecontrol switch 16 whereby asingle operation of the switch 16 will serveto open`V or close the window as the case may be. a

The slot 47 form-ed in the door 6 to receive the locking bar extension46 is made suiii'cientlywide to insurev the entrancefof the extensioninto said notch when' the window is opened, the width of the strip 21being proportioned to the width ofthe notch 47 in such a way that thenotch 47 must necessarily be in position to receive the extension 46before contact is madebetween the strip 21 andthe contacts 19. Theprovision is made to insure the locking of the booth door 6 beforethejwindow canbe opened.

Freni the above explanation4 it will be noted that the window 3' isclosed at `all times when the door 6 i's unlocked, and that the door 6is locked at all times when the windowB is open'. rIhis arrangementprotects the teller .from observation of'persons other than theindividiial` within the booth and an attack by a number ofpersons inattempt to commit robbery is madel impossihle. At the samel time,l theperson within thexboothis locked inl such a manner that any personattempting to rob-or defraud the bank can be liept imprisoned within thebooth while officers are summoned to effect his arrest. The'arrangementthus forms a ine-ans for providingprotection to the teller and guardingagainst the escape `ofpersons attempting any felonous `act. In additionto the protection afforded, the arrangement affords privacy to thetransactions between the'teller and the customers of thebank. Y

The windows'l and booths 4 are preferably arranged in pairsas showninthe drawings soV that one window may be openedwhile the other windowis being closed. Customers will thusbe admitted into the boothsalternately and in this manner quicken the condiict o'f v the banksbusiness without de-` reo privacy aiiorded each customer. The number,and arrangement of, the windows and booths however must necessarily beadapted to the requirements of any particular bank.

In order to prevent a customer from being inadvertently locked in thebooth due to the failure ofthe -source of electrical power, I provide arecess 51 in the end of each bar 43 to be engaged by a square keyadaptedl to be inserted into engagement with said relcess through asmall aperture 53 formed in the adjacent panel of the cage. The keyparts shown in the drawings may of course be modiiied in'many wayswithout ldeparting from the spirit of the invention. I therefore do notWish to restrict myself to the precise constructionshown but desire toavail myself of all modifications which may fall within the scope ofthek appended claims. i Having thus described `my invention what I claimas new and desire to secure by Letters Patent is i1.
